OK, next question. I'm trying to use nextval/currval and I'm getting
this:
search_info=# select currval('state_vectors_id_seq');
ERROR: state_vectors_id_seq.currval is not yet defined in this session
search_info=# select id from state_vectors;
id
----
1
(1 row)
shouldn't the first select have returned 1? The state_vectors_id_seq
is the sequence created by declaring id SERIAL in the table
state_vectors, and I've done one INSERT INTO state_vectors VALUES
(nextval('state_vectors_id_seq'), ... ); which worked fine and is
where the 1 comes from. (I'm interested in finding out the value used
for the most recent insert, and currval seemed like a pretty painless
way of doing so.)
(I'm basing this on 4.15.2 of the postgresql faq kindly supplied
earlier.)
